| description | [Objective:] To investigate the incidence rate and clinical characteristics of supernumerary teeth in the anterior region of lower jaw. [Methods:] Patients who came to Suzhou Stomatological Hospital from January 2019 to October 2022 were retrospectively analyzed, and the occurrence of supernumerary teeth in the anterior region was observed and recorded. SPSS 24.0 statistical software was used to analyze the data. The medical records of the patients with supernumerary teeth in the anterior region were reviewed and recorded. [Results:] A total of 75 patients with supernumerary teeth in the anterior region of lower jaw were finally included. The incidence rate of supernumerary teeth in the lower anterior region was 0.99‰ (75/75 465). Boys (31 subjects) were less than girls (44 subjects), and the difference between the genders was not statistically significant (P>0.05). Features of supernumerary teeth in this group: Mixed dentition, one supernumerary tooth, root undeveloped, unerupted supernumerary and vertical positive growth accounted for 48.00%, 92.00%, 65.43%, 65.43%, 90.12%, respectively. Supernumerary teeth resembled mandibular incisors, canines or premolars in morphology. Overcrowding of lower anterior teeth accompanied by supernumerary teeth accounted for 52.00%. The incidence of impacted adjacent permanent teeth, delayed eruption and residual deciduous teeth was 12.00%. Patients were also accompanied by supernumerary teeth in primary dentition, congenital absence of deciduous and permanent teeth, fused teeth of deciduous and permanent teeth, supernumerary teeth in other parts, and even dentigerous cyst. 35 out of 75 subjects received extraction of anterior supernumerary teeth and/or orthodontic treatment in our hospital. [Conclusion:] Clinically, supernumerary teeth in the lower anterior region are rare and can affect the appearance and oral function, which should be paid attention to by dentists. Patients often need multidisciplinary treatment to achieve satisfactory results. |
